After a stint in the Marines, he worked in repertory theater, and in 1957 he played the title role in a New York production of "Richard III." That part earned him critical accolades and led to film roles, beginning with The Hanging Tree (1959). Scott then racked up Oscar nods for his supporting turns in Anatomy of a Murder (1959) and The Hustler (1961). The pugnacious star proved equally adept at comedy with memorable portrayals in Dr. Strangelove (1964), The Flim-Flam Man (1967) and Oklahoma Crude (1973).
While Scott's big-screen appearances waned after 1980, he landed plenty of television work, including roles in the remakes of The Murders in the Rue Morgue (1986) and 12 Angry Men (1997). Scott died Sept. 27, 1999.
